Our finding of a strong association between RARS and low gene expression levels of ABCB7 also raises the possibility of therapeutic approaches for RARS using drugs which induce the expression of ABCB7, for example, carbamazepine has been shown to induce ABCB7 in the liver of epileptic patients treated with the drug [26]. The gene discussed is ABCB7; the disease is myelodysplastic syndrome with ring sideroblasts.
